Final Cut Pro and After Effects is what I use, religiously.
But if you're on a PC, you're BEST bet is Adobe Premiere. Premiere has the closest layout to FCP and if you end up getting more serious with editing and upgrade to a mac, you'll adjust easier to using FCP.
After Effects is a whole different story though.. You can rock it on a PC. Doing the time-remapping (transworld slowmos) is pretty simple, but everything else is confusing as fuck at first.
